Nowadays, our living and consumption levels are constantly improving with the development of science and technology, and the waterproof requirements for some high-end electronic devices, such as smartphones, are also constantly increasing.
Today we will learn about the material of waterproof and sound-permeable membrane for mobile phone receivers.
Waterproof and breathable membrane (also known as PTFE membrane) is a new type of polymer waterproof material. It has breathable, waterproof and oil-proof functions due to its microporosity, hydrophobicity and oil repellency. It has been widely used in medical, precision electronics, LED outdoor lighting, automotive lights, communications, chemical industry, security and other industries.
In terms of production technology, the technical requirements of waterproof and breathable membranes are much higher than those of ordinary waterproof materials; in terms of quality, waterproof and breathable membranes have functional characteristics that other waterproof materials do not have.
The waterproof and sound-permeable membrane of the mobile phone handset is made of polytetrafluoroethylene material through special processes such as mixing, extrusion, extrusion, calendering, and bidirectional stretching.
The porosity of this membrane can reach more than 88% or even higher, and this membrane has 1.4 billion micropores per square centimeter, with a pore size range of 0.1um-0.5um. The high-efficiency filter paper has high and low temperature resistance ( -200℃-260℃), no aging, no splitting, no discoloration, and strong weather resistance after long-term use.
It is a manufacturer of waterproof and sound-permeable membranes for mobile phone handsets that integrates production, sales and customization.
The company has advanced ptfe film production lines and composite production lines.
The company’s products are widely used in various fields. With strong technical force and strict management system, the company ensures that everything focuses on the interests of users and provides users with high-tech, high-quality, high-performance, and high-level products.
